User Control - best way for custom properties - is this correct?

Hi all, I know you've probably seen this many times before and I apologize but I've been reading around the internet and cannot find one simple solution to this.

I'm trying to make a user control that looks like this: 

I understand I'm going to need dependency properties for this, which will be the following:

- Client name (string)
- Client text status (string)
- Status (Enum - Online, Offline)
- Selected (bool - this will set the tick icon)

I've started making the control and this is what I have so far, it works but I'm unsure if some of the background code should be XAML or not?

XAML

<UserControl x:Class="ControlTest.MyControl"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             mc:Ignorable="d" 
             d:DesignHeight="34" d:DesignWidth="395" Height="34" Width="395"><Grid Background="#FFF8F8F8"><Grid.ColumnDefinitions><ColumnDefinition Width="34*" /><ColumnDefinition Width="361*" /></Grid.ColumnDefinitions><Label Content="Demo Text" HorizontalAlignment="Left" Margin="8,8,0,7" Name="lblClient" Grid.Column="1" Padding="0" HorizontalContentAlignment="Left" VerticalContentAlignment="Center" /><Ellipse Height="8" Margin="0,0,0,0" Name="elipStatus" Width="8" Fill="#FF44C137"><Ellipse.Stroke><SolidColorBrush /></Ellipse.Stroke></Ellipse></Grid></UserControl>

            InitializeComponent();
        }

        public string ClientText
        {
            get
            {
                return (string)GetValue(InfoTextProperty);
            }
            set
            {
                SetValue(InfoTextProperty, value);
            }
        }

        public static readonly DependencyProperty InfoTextProperty =
           DependencyProperty.Register(
              "ClientText",
              typeof(string),
              typeof(MyControl),
              new FrameworkPropertyMetadata("Demo Text",
                 new PropertyChangedCallback(ChangeText)));

        private static void ChangeText(DependencyObject source, DependencyPropertyChangedEventArgs e)
        {
            (source as MyControl).UpdateText(e.NewValue.ToString());
        }

        private void UpdateText(string NewText)
        {
            lblClient.Content = NewText;
        }
    }
}

Questions

1) Should I change the UpdateText() function to be using XAML instead - maybe on the label have: Content="{Binding Path=ClientText}" 

The issue with that though is that it doesn't update the designer when I change the property on the control itself within my window. It does however change the text when I run the application - is there any way to solve this or is it best left as behind code?

2) This is probably the biggest issue I'm having. I want to be able to do something like this.

<Trigger Property="Status" Value="Online"><Setter TargetName="elipStatus" Property="Fill" Value="#44c137" /></Trigger><Trigger Property="Status" Value="Offline"><Setter TargetName="elipStatus" Property="Fill" Value="#cd4848" /></Trigger>

I know that doesn't work because I tried it in the <UserControl.Triggers> because it can't find the custom property. I was wondering, should I make this a CustomControl instead? I know how to do it that way, but wasn't sure what control this would extend. Or should I use c# code to change the ellipse fill when the value is change?

Any clarifications on this would be greatly appreciated. I'm sorry for hte long thread, thanks
